[0024] The specific implementation methods of the present application are described below by way of examples:
[0025] like Figures 1 to 5As shown, the embodiment of the present application provides an electronic connector, including: a housing 100, the housing 100 has a connecting channel 160, the housing 100 includes a connecting portion 120, the connecting portion 120 surrounds at least part of the connecting channel 160; a plug assembly 200, at least part of the structure of the plug assembly 200 is inserted into the connecting channel 160, and the connecting portion 120 is arranged around the plug assembly 200; a fastener 300, the fastener 300 is connected to the connecting portion 120; wherein the connecting portion 120 is provided with a connecting hole communicating with the connecting channel 160, and the fastener 300 is embedded in the connecting hole to fix the plug assembly 200. Specifically, the housing 100 is an integrally formed structure obtained by mold injection, and is generally made of plastic. The housing 100 further includes a plug-in portion 110, which is connected to the connecting portion 120. A connecting passage 160 passes through the plug-in portion 110 and the connecting portion 120, so that the plug-in portion 110 and the connecting portion 120 respectively surround at least a portion of the space of the connecting passage 160. The plug-in portion 110 is used to connect or clamp the port of the device, thereby achieving a fastened connection, thereby preventing the connector from falling off; the connecting passage 160 is used to fix the connection of the plug-in assembly 200, thereby preventing the plug-in assembly 200 from shaking during the connection process; and the connecting portion 120 is used to fasten the connection between the plug-in assembly 200 and the signal line 400, thereby improving the anti-bending ability of the signal line 400.
[0026] like Figure 1 As shown, in the embodiment of the present application, the plug assembly 200 includes a plug connector and a PCB board, and the plug connector is welded to the relevant pins of the PCB board. It can be understood that the PCB board is the carrier of the electronic components inside the connector, and each circuit is connected by wiring of copper wires and other conductive elements. The PDB board provides a physical connection between electronic components and a path for the transmission of electrical signals. And the PCB board serves as a structural skeleton of the connector, providing stability and mechanical support for the connector. At the same time, the layout design of the wires and electronic components on the PCB board helps to achieve high-speed signal transmission, and the electronic components, capacitors and resistors set on the PCB board can be used for signal control and management, and for enhancing signal quality, filtering, isolation and current control functions. The PCB board is also provided with a ground wire and a shielding layer to provide shielding protection against electromagnetic interference, thereby helping to reduce interference noise and maintain the integrity and stability of the signal. Depending on the type of transmission signal, the plug assembly 200 meets different connection protocols, and the type of specific protocol can be selected according to the usage scenario. The embodiments of the present application are not listed in detail here.
[0027] like Figure 1 and Figure 2As shown, in the embodiment of the present application, the connection part 120 includes a plurality of connection plates connected end to end, and at least two or more connection plates are provided with connection holes. Specifically, the connection strength of the connection part 120 is improved by the plurality of connection plates connected end to end, and the connection plates are mutually pulled to disperse the pressure applied by the outside, thereby improving the overall bearing capacity of the connection part 120. At the same time, the connection hole is set on the connection plate, and after the fastener 300 is connected with the connection hole, it can be matched with the connection plate, thereby improving the tensile strength of the fastener 300, avoiding the fastener 300 from being separated from the connection hole when being bent by external force, thereby enhancing the anti-bending ability of the fastener 300, and avoiding the electronic connector from breaking during use.
[0028] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the connecting portion 120 includes a first plate 121, a second plate 123, a third plate 122 and a fourth plate 124 connected end to end in sequence; wherein, the connecting holes include a first connecting hole 130, a second connecting hole 150 and a third connecting hole 140, the first connecting hole 130 is located in the first plate 121, the second connecting hole 150 is located in the second plate 123, and the third connecting hole 140 is located in the third plate 122. Specifically, with the third plate 122 as the bottom plate, the first plate 121 and the third plate 122 are arranged opposite to each other, and the second plate 123 and the fourth plate 124 are respectively connected to the opposite sides of the first plate 121 and the third plate 122. Thus, the first plate 121, the second plate 123, the third plate 122 and the fourth plate 124 form a continuous integral structure, namely the connecting portion 120. The first plate 121, the second plate 123 and the fourth plate 124 are provided with a first connection hole 130, a second connection hole 150 and a third connection hole 140 respectively, while no connection hole is provided on the third plate 122. This design can reduce the number of sliders used in the mold when the connection part 120 is injection molded, thereby reducing the cost used in developing or assembling the mold. At the same time, the injection molding process of the electronic connector can also be reduced accordingly, thereby reducing the production cost of the electronic connector from multiple aspects. It can be understood that the fastener 300 can improve the bending resistance and pulling resistance of the electronic connector after being engaged with the first connection hole 130, the second connection hole 150 and the third connection hole 140, thereby avoiding the electronic connector from breaking during the bending and pulling process, thereby extending the service life of the electronic connector.
[0029] In some other embodiments of the present application, the connecting part 120 may also include three, five or more plates connected end to end in sequence. The overall strength and bending resistance of the connecting part 120 are improved by forming an overall structure with multiple plates, thereby improving the anti-fracture ability of the electronic connector. Therefore, the specific number of plates that make up the connecting part 120 can be selected according to the actual usage scenario. The embodiment of the present application only lists the case of a combination of four plates, and other cases are not listed in detail here.
[0030] like Figure 2 As shown, in the embodiment of the present application, the second connection hole 150 and the third connection hole 140 both penetrate the first plate body 121 and the third plate body 122 along the third direction Z. Specifically, the first connection hole 130, the second connection hole 150 and the third connection hole 140 both penetrate the first plate body 121, the second plate body 123 and the fourth plate body 124 in the direction of the connection channel 160, so as to be connected with the connection channel 160. When the fastener 300 is attached to each connection hole, the fastener 300 can use the entire plate body where each connection hole is located as a supporting carrier, thereby improving the connection strength between the fastener 300 and the connecting portion 120. The two sides of the second connecting hole 150 and the third connecting hole 140 also penetrate the first plate body 121 and the third plate body 122 along the third direction Z respectively, so that when the fastener 300 is in contact with the second connecting hole 150 and the third connecting hole 140, a larger contact area and force-bearing area are obtained, further strengthening the connection relationship between the fastener 300 and the connecting part 120, and further improving the bending and fracture resistance of the electronic connector.
[0031] like Figure 2 As shown, in the embodiment of the present application, the first plate body 121 is provided with a first connection groove 131, and the first connection groove 131 is communicated with the first connection hole 130; the second plate body 123 is provided with a second connection groove 151, and the second connection groove 151 is communicated with the second connection hole 150; the fourth plate body 124 is provided with a third connection groove 141, and the third connection groove 141 is communicated with the third connection hole 140; the first connection groove 131, the second connection groove 151 and the third connection groove 141 all extend toward the fastener 300. Specifically, the width of the first connection groove 131 is the same as the width of the first connection hole 130; in some other embodiments of the present application, the width of the first connection groove 131 may also be larger or smaller than the width of the first connection hole 130. The widths of the second connection groove 151 and the third connection groove 141 are both smaller than the widths of the second connection hole 150 and the third connection hole 140; the widths of the second connection groove 151 and the third connection groove 141 are the same; in some other embodiments of the present application, the widths of the second connection groove 151 and the third connection groove 141 may also be different.
[0032] like Figure 2As shown, in the embodiment of the present application, the fastener 300 includes a first connecting block 320, a second connecting block 330 and a third connecting block 350, the first connecting block 320 is cooperatively connected with the first connecting hole 130, the second connecting block 330 is cooperatively connected with the second connecting hole 150, and the third connecting block 350 is cooperatively connected with the third connecting hole 140. Specifically, the first connecting block 320 is filled in the first connecting hole 130, and the four outer side surfaces of the first connecting block 320 are fitted with the four inner walls of the first connecting hole 130; the second connecting block 330 is filled in the second connecting hole 150, and along the first direction X, the first side surface and the second side surface of the second connecting block 330 that are opposite to each other are respectively fitted with the two inner walls of the second connecting hole 150, and along the second direction Y, the two bottom surfaces of the second connecting block 330 facing the connecting channel 160 are fitted with the two bottom walls of the second connecting hole 150; the third connecting block 350 is filled in the third connecting hole 140, and along the first direction X, the third side surface and the fourth side surface of the third connecting block 350 that are opposite to each other are respectively fitted with the two inner walls of the third connecting hole 140, and along the second direction Y, the two bottom surfaces of the third connecting block 350 facing the connecting channel 160 are fitted with the two bottom walls of the third connecting hole 140. As a result, the three connection blocks are tightly fitted with the three connection holes, thereby strengthening the connection relationship between the fastener 300 and the connection part 120, and further improving the bending and fracture resistance of the electronic connector.
[0033] like Figure 3 and Figure 4 As shown, in the embodiment of the present application, the fastener 300 further includes a base 390, the first connection block 320 is connected to the base 390 via a first connection column 380, the second connection block 330 is connected to the base 390 via a second connection column 340, and the third connection block 350 is connected to the base 390 via a third connection column 360; wherein the first connection column 380 is fitted with the first connection groove 131, the second connection column 340 is fitted with the second connection groove 151, and the third connection column 360 is fitted with the third connection groove 141. Specifically, the first connection column 380, the second connection column 340 and the third connection column 360 are used to fix the first connection block 320, the second connection block 330 and the third connection block 350 to the base 390. When the electronic connector is stretched and bent by external force, the first connecting block 320, the second connecting block 330 and the third connecting block 350 can form effective restraint through their respective connecting holes, and the first connecting column 380, the second connecting column 340 and the third connecting column 360 have corresponding deformation capabilities, so that the electronic connector has a certain deformation ability when stretched and bent, thereby avoiding the electronic connector from breaking.
[0034] like Figure 3 and Figure 4As shown, in the embodiment of the present application, the plug assembly 200 is connected with a signal line 400, and the fastener 300 further includes a fixing ring 370, which is connected to the side of the base 390 away from the first connection block 320, and the fixing ring 370 surrounds the peripheral side of the signal line 400 and fixes the signal line 400. Specifically, the signal line 400 is connected to the corresponding pin on the PCB board, and the signal line 400 is used to transmit data signals. The fixing ring 370 wraps the connection between the signal line 400 and the PCB board, thereby preventing the signal line 400 from breaking after being bent multiple times during use. It should be noted that after the plug assembly 200 is placed in the connection channel 160, the connecting part 120 with the plug assembly 200 is placed in the injection mold, and the plastic encapsulation material is injected into the injection mold to form a fastener 300 tightly connected to the connecting part 120. The peripheral side of the fastener 300 is flush with the peripheral side of the connecting part 120. After the fastener 300 is plastic-sealed, a limit block 310 will be filled in the connecting channel 160. The limit block 310 surrounds the circumference of the PCB board or the signal line 400 to limit the position of the PCB board or the signal line 400 to prevent the PCB board or the signal line 400 from being damaged during movement.
